This could be as simple as a loose connection to your battery. If one of the terminals is loose then you'll have erratic behavior and spells of running well and then poorly. I'd check the terminals and tighten them well. While you're there coat them with a battery terminal grease, or if that's not available use WD-40, to ward off corrosion and give you a better contact.
You don't state why you replaced the battery but there's the chance that the real fault was your alternator. If your alternator is going bad then you'll have symptoms like you describe and also may think your battery is at fault and replace it. The issues will return after the battery's charge dwindles and your alternator cannot maintain it. Most auto parts stores will do a free alternator test for you, but most will need it removed and brought to their counter to do this. Well worth the test, and if it tests bad, then you can get the discount for the returned bad core unit on the spot.
Hope this helps.

Look for rotten or broken vacuum lines around the throttle body and the EGR rail. Also, if you have a two tank system, wiggle the tank selector switch from front to rear several times and then try starting it again and see how it runs. If it seems to clear the problem, run for a few days and then replace it. This was my problem. A $12 part and it would also give erratic engine codes. It would run excellent after a hard time starting and cut right out for no reason. It has to be something simple! A smooth running engine does not just quit. Also check the fuel pump relays (tapping them or swapping them cleans the contact surfaces and also check the wiring underneath the modules for any green corrosion or exfoliation) and associated wiring harnesses for damage or moisture or greasyness. A flashlight and mirror is useful for this. I can not empasize enough to check all over for vacuum leaks. Loose twisty hosing signals leaks too. replace or cut shorter to make a new seal. Good luck!

'90 Grand Am ,cuts out sometimes ,while droving,re-starts most of the time,but sometimes dont.Other times,while sitting a day ,wont starrt at all,although,engin cranks good


Sounds like you have a fuel flow problem. Replace the fuel filter and check the fuel pump pressure.

I would suspect the fuel pump or bad gas if it seemed to run good on the flats and downhill but then cuts out going up a sizeable hill.

You, my friend have a flat battery.

However, replacing the battery will not fix the problem, the battery is just a symptom, just like having cough syrup won't fix a cold, it will ojnly make your throat feel better.

What you need to do, is replace the battery, then get a multimeter, and check the voltage of the battery when the car is running at idle (in park/neutral), it should be 13.2-14.4v. If below this, im suspecting 12.0v or below, then you will have to have your charging system (alternator) checked.

Sounds like you don't have a good ground at the battery. Take the clamps off of the battery and give them a good cleaning. Then, put some dielectric grease on the battery posts when you put the clamps back on.
